This editorial cartoon most likely refers to
a) the voting rights act.
b) plessy v. ferguson.
c) the twenty-sixth amendment.
d) brown v. board of education.

I think it would have to be brown vs. board of education. That was a case about segregated schools.

The case was a u.s. supreme court decision that defined the scope of the u.s. congress's legislative power and how it relates to the powers of american state legislatures. the dispute in mcculloch involved the legality of the national bank and a tax that the state of maryland imposed on it.
